In the foothills near Tribulation, Red Harlock’s men open fire on Cruz and Emmett, but they fight off their attackers with lead and fists. Red tries to rally his men, but his manoeuvre backfires and he falls at Cruz’s feet, humiliated and humbled. The owlhoots flee and Cruz and Emmett tie Red up and take him back to town. Glend watches all this from hiding.
Meanwhile, Elijah communes with the ghost of Samuel Colt, who speaks of a familiar vibration in the ether – Fancy, the woman who killed Colt, is coming to town. He tells Elijah to find a ‘rich vein of minerals carved from another time’, from which Colt meant to craft a mighty firearm. Before the ghost can continue, Sarah bursts in to demand that Elijah discover what hold Delian has over Glend.
Emmett and Cruz bring in Red, and Elijah locks him in a cell. Emmett wants to leave rather than be interviewed, but something in the sheriff’s office knocks the wind from his sails. Elijah gets the story from both of them as Red secretly whispers to an accomplice through the cell window, instructing him to ‘switch to Plan B’. When Elijah intimidates Red to assert his authority, he accidentally makes reference to his past; Red doesn’t notice, but Emmett does.
Glend reports to Delian, who apologizes for his previous anger and shows him what was brought in on his private train – an ancient, ornate wooden coffer made of oak and brass. Delian ‘took possession’ of it some years ago, and credits it with the Agency’s rise to power – all their psychically active devices carry slivers of crystal from inside what Delian calls ‘The Box’. It has apparently existed since the time of the Crusades, but Delian is searching for an even greater source of power. He also needs an inventor to work with the crystal (something Samuel Colt once did), and Delian and Glend plot to bring Emmett on board.
Elijah arrives to discuss Glend’s threats against Sarah. Glend attempts to convince Elijah that Sarah is overreacting, pushing with his mind control powers; Elijah resists, but in doing so leaves an echo of his centuries of experience in Glend’s mind. Glend manages to implant a post-hypnotic suggestion in Elijah’s mind to leave the matter lie. Before they can talk more, a porter from the hotel bursts in to tell them that Delian’s train has been stolen.
Back in the Sherrif’s office, Cruz questions Red Harlock, who confesses that he’s looking to crash and rob a US Army train carrying soldiers’ wages to Port Union in the north. He was hoping to do so with a massive rockslide, but now must go to Plan B – his men have stolen Delian’s private train and are going to ram the Army train! Meanwhile, Emmett discovers Elijah’s back room and its ancient Templar shield, and is psychically overwhelmed by its great age. While unconscious, he’s contacted by the ghost of Samuel Colt, who insists that Emmett is in Tribulation for a reason, though Emmett doesn’t believe in fate or destiny. Colt mentions the Box, but just as the ghost is about to reveal its location, Cruz wakes Emmett and insists they try to stop the train.
All four men ride hard to catch up to Delian’s train, which is now speeding towards the Union money train. Elijah and Cruz open fire on Harlock’s men, while Glend and Emmett make their way onto the train. Glend sneaks through the train and discovers a map annotated by Delian, with notes regarding Tribulation, the abandoned orphanage south of town, the Sierra Blanca Mountains, the Miagani Indian homelands and the Knights Templar. Emmett attempts to reverse the train, but instead locks its brakes into place, leaving it on a collision course. Finally, with an incredibly lucky shot, Cruz shoots the oncoming train and shoots the brake switch, stopping it just before the two trains collide.
In the aftermath of the battle, Elijah and Glend realise a greater level of respect for each other; Cruz stays at a whorehouse, gazing at a locket from his past; and Emmett bursts into Sarah’s office to say "’Tell me everything you know about Samuel Colt!’
